Looking to add an amplified sub to 2010 with factory JBL navigation. Would prefer to tap into wire at the factory JBL amp under the passenger seat since I'll be tapping into the speaker wires there for a high level signal. Saw several posts asking the same thing with no answers. Please help. Thanks in advance.
I have a powered sub, that's doing great. I don't have the JBL system, but for $111 (Amazon) the planet audio 8" powered sub really opens up the audio spectrum in a Prius. Posted via the PriusChat mobile app.
